The hackers are looking for information on everything from electronics to plant seeds—anything to put Chinese manufacturers on an equal footing with those from the United States which did the original research and development on a product.

China’s intelligence services are “as aggressive now as they’ve ever been,” FBI Assistant Director Randall Coleman, who runs the bureau’s counterintelligence division, said at a recent news conference, according to The Daily Beast. Coleman said the number of industrial espionage cases investigated by the FBI in the past year is up 53%. An FBI survey of 165 companies showed that half had been targeted by foreign spies and the Chinese were suspected in about 95% of those cases.
